find the number of times a pair of value is a struct

Hi, I have a struct of data Clusters3 with dimension [22x1]. I'm interested to find if the pair of value in o (attached)[6 2] are presents in the first two column of Clusters3.users. I want as output a matrix A [22 6] in which is represented for every element of Cluster3 if the six pairs of value in present or no in Clusters3.users

Example
A(1,1) hold the number of times the pair in o(1) is present in Clusters3(1).users(:,1:2);
A(1,2) hold the number of times the pair in o(2) is present in Clusters3(1).users(:,1:2); 
A(1,3) hold the number of times the pair in o(3) is present in Clusters3(1).users(:,1:2); 
etc

I have tried

for i=1:size(o,1)
c(i)=find (Clusters3(1).users(:,1:2)==o(i))
end

but it gives errors.

I have also try

structfun(@find, Clusters3.users, o(1))

but it doesn't run

Can you help me? thanks

One of many ways to do this:

A = zeros(size(Clusters3, 1), size(o, 1));
for crow =  1:numel(Clusters3)
   for orow = 1:size(o, 1)
      A(crow, orow) = sum(ismember(Clusters3(crow).users(:, [1, 2]), o(orow, :), 'rows'));
   end
end

You may want to use ismembertol with an appropriate tolerance instead of ismember since you're comparing floating point values.

Your example data is not very useful since only cluster3(1) has any match.
